Public bug reported:

We have many unit tests (simple example[1]) that check to see that indexes are case insensitive. The problem is that our current implementation doesn't explicitly make the index case insensitive. That's left up the the RDBMS. This is problematic because in my testing I have seen different results:
  - SQLite - is case sensitive
  - MySQL - is case insensitive[2]
  - PostgreSQL - is case sensitive

My goal was to get the unit tests working on MySQL/PostgreSQL, so I
would like to figure out a direction. Should we drop those tests and
leave it up to the environment? It's also possible to get SQLAlchemy
create the proper index. I've never done it, but I'm sure it's possible.
